I am getting my 2008 GT/CS within the next week or so and decided on getting stick. I am getting it loaded and wanted to know if it is worth it to get the 3.55 axel option? Does it make the car faster and better handling? Or in what case does it improve the car?

If I had to do it again (note that I did have 3.55s at purchase) and pay extra for the 3.55s my answer would be No. And here's why - if you are into Modding at all you will soon be paying again for either 3.73s or 4.10s.

I was looking for a Mustang GT with 3.31s so I could upgrade to 3.73s, but the only one that could find with the options I was looking for had the 3.55 option.
After having the stock 3.55s for a couple of months, I am pleased with the performance. I did a few mods (see sig) that actually helps the car accelerate better, so I will be sticking with the 3.55s (not worth it going to 3.73s from 3.55s).
Note: My car is a daily driver that may never see the drag strip. If I was a regular at the track, I would definetly go with 4.10s.

There is a noticeable difference with 3.73 from 3.55, I can say from experience!

Given only the choice between 3.31's and 3.55's, I would say yes. Fortunately, thse aren't the only two choices:
If you're on this forum, you're going to be modding your car sooner rather than later. And then you'll pay to have 3.73's or 4.10's installed. So no, I don't think it would be worth it. Save the money to get the shorter gears.
Sounds like I got a choice to make. I am def going to upgrade gears and other mods because I can't wait! I might jus stick with the 3.55's for now to get better acceleration but then I will g2 3.73's. Since it will be daily driven, I see no point in putting 4.10's.
Mine came stock with 3.55's. I now have 4.10's and couldn't be happier. It's my daily driver, and I've put on almost 50k miles in 2 1/2 years.
I don't know if I would've been happy stepping down one gear size, I don't know that it would have been as enjoyable a difference. Going two sizes is freakin' awesome. I love the power to the wheels.
If I were you, I'd save my money, and then go for the 3.73's later like you said, but if you were me, you save your money and go for 4.10's and and some whitening toothpaste, because you'll have a permanent grin on your face.
